with the overall error, which gives the range, asdiscussed in class. Does the accepted value of f fall
within the range centered at the best value? Hint: Check iffmin
<facc
< fmax, where fmin
is the minimum possible using the values of the uncertainty and plugging into
the formula by subtracting the uncertainty in the numerator and adding the uncertainty in the
denominator; similar reverse logic should be used to get fmax:
add in the numerator and subtract in
the denominator.
